- Accuracy and reliability: At 19,000 Lux (1,999 FC) the readings are +/- 4%. At 199,999 Lux (19,999 FC) the readings are +/- 6% of readings plus or minus 10 digits. - Fast, real-time measurements: 2-3 times per second sampling to instantly show how much luminosity you are getting, helping you avoid guesswork. - Wide range with fine resolution: The meter measures luminance from 0.01 to 199,999 Lumens and from 0.01 to 19,999 Foot Candles, with a resolution of 0.01. - Flexible sensor design: The light sensor rotates 360 degrees and the probe is removable, so you don’t need to turn the light meter around to measure illumination from different angles. Just rotate the sensor and you can still read the illuminance at the front. - Practical use scenarios: - Photography and video production: verify and maintain consistent lighting levels on set for accurate exposure. - Indoor horticulture: monitor and adjust grow lights to optimize plant growth conditions. - Workplace and display lighting: check illuminance to meet safety and presentation standards in offices, studios, or galleries.
